Apple helped Walmart build a store-within-a-store oasis for Apple products in the home state of the chain’s founder Sam Walton.

We broke the news earlier this year that Sams’s Club is exploring Apple Store-within-a-store concepts. This weekend, Apple retail news website ifoAppleStore posted numerous pictures from a Walmart in Lowell, Ark., which owns and operates Sam’s Club, that depict Apple displays within its walls akin to Best Buy’s lavish store-within-a-store creations.

Today only, Best Buy takes 20% offselect iTunes eGift Cards, as listed below. We saw Walmart has a similar deal last week but only on $50 denominations. Note that international US iTunes users are eligible to purchase because the gift cards will be emailed for redemption but must use a US credit card or Paypal.

For a few more hours, Walmart is offering the $50 iTunes gift card for $40. That’s 20 percent off and the lowest price yet. The card comes immediately through email, and it counts toward free shipping on other items. It can be purchased for use in the US iTunes Store on iBooks, Mac and iOS Apps, Music, Videos, Movies and more.

Limit two per customer (You can get around the 2 per customer limit if you have multiple credit cards). International readers are telling us that their foreign credit cards are rejected (though US based Paypals are working).
